In Vivo Dynamic D2O-MRI for Quantifying Apparent CSF Water Renewal Across Ventricular and Extraventricular Compartments.
PURPOSE The choroid plexus has long been regarded as the principal source of cerebrospinal fluid (CSF), yet this view remains unresolved. We developed a dynamic indirect D2O MRI approach to quantify regional apparent CSF water renewal in vivo in rats at 9.4 T. METHODS Rats were scanned at 9.4 T using spin-echo echo-p...
